Graphical Modeler Raster layer Input does not recognize GRASS raster file #21457

Closed qgib closed 5 years ago

Author Name: Wes Kent (Wes Kent) Original Redmine Issue: 13408 Affected QGIS version: 2.8.3 Redmine category:processing/modeller Assignee: Victor Olaya

In a created model using the Graphical Modeler, the model will not recognize/allow use of a GRASS raster layer as a Raster layer input. The GRASS raster layer has been added to the QGIS project, but it does not appear as an input option to use in the Raster layer drop-down list of the model. GRASS vector layers are recognized/allowed, and work fine, as Vector layer inputs for the model.

Not a bug. Grass raster layers are not supported as inputs for Processing algorithms

Thank you for the information. When using the GRASS tools available in the Processing Toolbox, I am able to use GRASS raster layers as input layers; so it seems that the functionality to accept GRASS raster layers as input files is already in QGIS. With the raster processing capabilities of GRASS, and with there being 100+ GRASS raster processing tools in the toolbox, the ability to create Processing algorithms/models that include these powerful tools would be a worthwhile feature to have in QGIS.

see #16635

(on Windows and Linux GRASS raster layers are not yet shown as available inputs, when it will then is expected them to work in any place in Processing).
